For those owners however, who live and die by bench racing stats, there's hope in the form of a little electrical box that no other high end sport sedan will be able to touch you.
The HKS speed limiter wires simply into the cars ECU and frees it from the constraints of an artificial speed limit. Left with only the world at hand to determine just how fast the car can go, the IS-F instantly trumps it German competitors in the one area they'd be expected to be at an advantage.
Top speed.
Considering the stock car was limited to 170 mph while the Germans use their de rigueur 155 mph limit, it seems a lot like kicking a man when he's down
Our take? It would be a sweet sight to see one of theses cars pass an M3 or C63 on an unrestricted section of the autobahn at full speed
